A manhunt involving multiple law enforcement agencies was underway early Thursday after three police officers were shot -- one fatally -- in Riverside County. Authorities believe that the suspect is a former Los Angeles police officer already wanted in connection with two Orange County slayings.
The suspect, Christopher Jordan Dorner, 33, wrote an online manifesto threatening to harm police officials and their families, authorities said, and he is considered "armed and extremely dangerous."
